Which Test Cases to Automate?


Tests that need to be run for every build of the application (sanity
check, regression test)



Tests that use multiple data values for the same actions (data driven
tests)



Stress/load testing



Tests requiring a great deal of precision



More repetitive execution!

Better

candidate for automation.

QTP


An Introduction


Quick Test Professional is the flagship functional testing tool from
Mercury Interactive.



It is an icon based tool, which automates the functional & regression
testing of an application.




QTP is easier to use and implement for both technical & non
technical testers in comparison to other functional testing tools
available.



Latest Available versions is QTP 10.0

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Salient Features


Scripting Language is
VBScript
which is easy to use , understand
and program even complex functionalities with ease..



Uses “
Active Screen”

technology to record scripts which aids the
tester in referring to the screens object properties.




Library files contains
VBScript functions and subroutines

that can
be added to the test.



Support
Modern
Development Environment.

Test Object Model


This is a large set of object types or
classes
that Quick Test uses to
represent the objects in AUTs


Properties


Methods



A
test object

is an object that


-

represents the actual object


-

stores information about that object.



A
run
-
time object

is the actual object in the AUT.


>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Test Object Model



QTP Test Object

Modeling

Test Object

Run Time Object

Quick Test Professional maps the Run Time Object to
a Test Object already present in its repository.

Once recognized it can repeat all our actions.

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Objects

HTML Code for the button CALCULATE


<INPUT id=button1 type=button
value=“Calculate” name= “button1” title=""
LANGUAGE=javascript onclick="return
button1_onclick()">


You may have called your button as
button1, but QTP recognizes it

with the name Calculate

Object Repository


>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Object Repositories

Object Repository



Object Repository acts as a translator between QTP script and the
Operating System ( similar to GUI map concept in win runner).



Types of Object Repositories



Shared Object Repository



Per Action Object Repository


>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Object Repositories

Per Action vs Shared Object Repository

Per Action Object Repository


Separate action repository for each
action.


If an object description changes, you
need to modify the object in every
action repository using that object.


No need for any Object Repository
administrator.


Preferred method if application won’t
change during renovation


Default Object Repository. Preferable
for novice QTP users.



Shared Object Repository


can use the same shared object
repository file for multiple tests.


If an object description changes, you
only have to modify in the shared
Object Repository


all tests will
playback properly.


Requires Shared object repository
creation and maintenance.


Crucial if application may change
during renovation


Most commonly used across
Automation projects.

Synchronization Points

What is a Synchronization Point?



A synchronization point is a line in the test script that instructs
QTP to wait for a certain response from the application during
playback.

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Why Synchronize?

Inputs
data to
AUT

Accepts

input

Run script

Sends data to
database
server

Attempts

Run script

With synchronization point

Synchronizati
on point

Waits for
server;
cannot

Waits

Synchronizati
on point

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<


Locate the lines in the script to insert the synchronization point



In Quick Test choose
Insert > Step > Synchronization Point
.
The mouse pointer turns into a pointing hand. This should be
done while recording.



Using the Hand Pointer click on the object to Synchronize.



Add Synchronization Point dialog box opens.



>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

How to Add Synchronization Points



Select the Property name and its corresponding value which you want to
use for the synchronization point.




Enter the synchronization point timeout (in milliseconds) and Click OK. A
Wait Property step is added to your test.


For e.g for this case the step inserted in the script will be

Dialog(“Login”).WaitProperty "enabled", 1, 10000

Test Parameterization

How Long Does it Wait?



TIME PARAMETER (test script)



+


Object synchronization timeout
(Test Settings)



=



TOTAL TIME


>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Why Parameterization ?


Parameterization allows us to pick different values at run time.



Reduces Time and Effort.



Usage of data drivers allow us to use the same data for various
input boxes.



Parameterization can also be done for checkpoints.


>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Parameterization Continues

1. The hard coded values can be made to vary.

2. The values will be taken from the excel sheet.

3. Right click on the object name and select method
arguments

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Global and Action Data Sheets


The
Data Table

contains two types of sheets:



Global sheet:
This enables you to share information from one action
to another. Should be used for data drivers and Output Values.



Action Sheet:

Each action also has its own sheet in the Data Table so
that you can insert data that applies only to that action.



When there are parameters in a current action’s sheet, you can set
Quick Test to run one or more iterations on that action before
continuing with the current global iteration of the test.

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Output Values


Used when the output for one action is to be used as an input for a
subsequent action.



This can be parameterized.




Even labels can be used as output values.

Actions

Actions


Actions can divide a test into several distinct business Processes.



Each actions signifies a logical independent test.



To divide a test into actions you can



Insert a New Action



Split an existing action into two Actions



Insert a copy of an existing Action



Insert a call to an existing Action



In this way several actions can be integrated to each other within
the test or across different tests logically.


>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Creating Actions

Click on the new
Action Icon

Enter the name of the
new Action and assign
its attributes

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Types of Actions


Reusable Action:


Can be reused in the same test multiple times.


Can be used in another test


Read Only


Parameter data can be from a


local excel (Editable)


original action sheet (Read Only)



Nested Action:


An action within an action.


Helps maintain the modularity of your test


Enables to run one action or another based on the results of a
conditional statement


>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Copy of an Action


A lightweight protocol for exchange of information in a decentralized,
distributed environment.



An XML notation for describing how messages are assembled and
transmitted over HTTP between service consumers (clients) and
service providers (servers)



XML based protocol that consists of three parts:


Envelope describes the contents of a message and how to process
it, and contain extra details such as security information or the final
destination of the message.


Header is a generic mechanism for adding features to a SOAP
message in a decentralized manner without prior agreement
between the communicating parties.


The Body is a container for mandatory information intended for the
ultimate recipient of the message.

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Call to an Action


Calls to actions are read
-
only in the calling test. They can only be
modified in the test in which they were created.



Enables you to use the same action in several tests and makes it easy
to maintain tests.



Can make calls to only “Reusable” actions.

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Integration of Winrunner,

QTP &

Test Director

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Why Integrate QTP ?


With Win Runner



Facilitates running Win Runner tests and call TSL functions in
compiled modules with parameters by creating calls to Win Runner
tests and functions.



With Test Director (TD)



TD, Mercury Interactive test management tool, can help you organize
and control the testing process. It provides an intuitive and efficient
method for scheduling and running tests, collecting test results,
analyzing the results, and managing test versions.

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

QTP & WinRunner


QTP can easily be integrated with Win Runner, Test Director and
Load Runner.



If the Winrunner is already installed and being used, then QTP can
be added without the loss of Winrunner scripts.



Quick Test Pro will be able to call Win Runner Scripts.



A single test can contain both Winrunner & QTP scripts.



>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Advantages of QTP over other
Functional Automation tools


Easy to use, icon based scripts. Easier

for non technical testers to
learn.



Usage of
VBScript
language for scripting which is very powerful ,has
lots of capabilities and can program even complex functionalities with
ease.



The active screen technology allows the person writing script to pick
-
up
values that may have been left out during recording. This helps to
reduce re
-
work for scripting.

>>>>>>>>>>>>>>>>>>>>>> www.softwaretestinggenius.com <<<<<<<<<<<<<<<<<<<<<<

Advantages of QTP over other
Functional Automation tools



Supports .Net, XML and other modern Environments.



Test Run Iterations/Data driven testing

is much easier and better
implemented with QTP.
Capturing output values

add data driven
testing more kick and flexibility.



Can create and implement the Microsoft Object Model (Outlook objects,
ADO objects, FileSystem objects, supports DOM, WSH, etc.).



Provides ability to trap exceptions and handle them using inbuilt
functions or user defined ones.
